selmerfudd My pump does not engage continuously ramping slowly to the pre-infusion pressure , it does so in smallish bursts and the pressure gauge also shows a pulsing of the pressure - I suspect that somehow the pre-infusion pressure is reached and then dissipates as the puck absorbs the water causing the pump to re-engage itself!
I suspect you are pulling the lever too slowly then, a video from you would help to see what you mean…..
See first video below for a quick view of what i mean…..
Last video shows the adjustment.
Adjustment is a combination of these 2 circled to position the “wedge” so it engaged the pump with very little movement of the lever.
BUT FULLY DISENGAGES THE PUMP WHEN THE LEVER IS IN THE RELEASE POSITION.
